I have quite a few hours on a DA40 NG in real life. I think generally this mod is pretty good, don’t have an issue with prop stopping. I think main improvements could come from the flight model side. In particular, I think in the sim it has a strong tendency to change pitch in gusty wind conditions, whereas in the real aircraft the effect is pretty mild in terms of pitch (it tends to yaw left and right if the air is quite unsettled).
On the runway it weathervanes way too much, but I am not sure if there’s anything that can be done about that as it’s a broader issue with the sim (though the A2A comanche seems to have improved but not entirely eliminated the problem). The real aircraft also has a castering nosewheel which means it’s more maneuverable on the ground at slightly higher taxi speeds when there’s more air passing the rudder. But personally I don’t think not simulating this is a big deal because it only affects the dynamics of slow taxi.
